Photocatalytic Degradation of Methylene Blue by Nickel Oxide Nanoparticles

NiO nanoparticles were synthesized by a chemical precipitation method using nickel nitrate as precursors and Sodium hydroxide as precipitating agent. The NiO nanoparticles have been successfully used as a photocatalyst for degradation of Methylene Blue dye from the aqueous medium. The synthesized nanoparticles were studied by powder XRD, FESEM, EDAX and FTIR spectroscopy. The powder XRD result revealed that the obtained samples were nickel oxide with face centered cubic structure. The particle size and the morphology of NiO nanoparticles were studied by the FESEM. The EDAX and FTIR analyses confirmed the formation of NiO nanoparticles. The Photocatalytic degradation study results revealed that the NiO nanoparticles are potential photocatalyst in degradation of Methylene blue. (C) 2017 Elsevier Ltd. All rights reserved.
